We are continuing to make our large list experiences better, please keep the feedback coming.

Spring 2018 update:
- We now support being able to manually add indexes to lists of any size (increased from lists up to 20,000 items previously).
- Starting with the February release of the Office 365 Excel client, you will be able to export your full list instead of getting cut off part of the way through.

What we are working on now:
- Predictive indexing will start to work for lists larger than 20,000 items so your views will automatically cause the right indexes to be added to your lists.

In our backlog:
- Being able to index/sort/filter by lookup column types (like person, lookup or managed metadata columns) without being throttled.
- Making sure that our REST APIs support querying in ways that will guarantee that the call will not be throttled.

For a general update on large list capabiltiies, the video on myignite.microsoft.com/videos/53861 (focusing on large lists at 42 minutes and 25 seconds) describes some of the changes that we delivered back in the second half of 2017:
- Modern UI now has a lot of support for adding indexes to large lists and libraries on the fly, reducing the number of throttling errors experienced by our users, and some new UI for browsing through items in large lists with our paging model
- SharePoint runs predictive indexing jobs to automatically add indexes as lists get larger based on your view definitions, and updates these indexes when you add/update your views

Looking forward to receiving more of your feedback.
